Drambuie is a liqueur that blends whisky with spices and honey and rose to prominence as the key ingredient in Frank Sinatra’s favourite cocktail, the Rusty Nail.
Stella David, chief executive at William Grant and Sons, said: “We have a passion and a reputation for nurturing and building brands.
“Drambuie is a natural fit for our portfolio, it has a very rich history and a great story to tell and we are delighted to be in a position to start to re-engage with existing drinkers and to connect the brand with an entirely new generation of consumers.
“We have always been secret admirers of Drambuie. We are very grateful to the MacKinnon family for entrusting the future of this iconic brand to our family, and we will do our best to make them proud in the decades ahead.”
Drambuie boss Michael Kennedy added: “We are pleased to complete this process with William Grant and Sons, a company who holds true those family values which will help nurture Drambuie to begin its next chapter of growth.
"As part of the William Grant and Sons stable of brands, we believe that Drambuie can truly achieve its potential as it will benefit from being part of a larger and more diverse organisation.
“I look forward to working with the team as we smoothly integrate the acquisition and help realise the benefits for both companies.”
